Conditions InDepth: Obesity

Obesity happens when the calories a person takes in are greater than the calories burned through activity and body functions.

Obesity is a body mass index (BMI) of 30 kg/m² or greater in an adult. BMI is a person's weight in kilograms divided by the square of their height in meters. Morbid obesity is a BMI that is higher than 40.
